HM Bluetooth module datasheet. System functionHow to wake up module from sleep mode?There are two ways to wake up module from sleep mode, if module was in sleepmode.7.1 Send “I am iron man, I am iron man, I am iron man I am iron .” string.Yes, that’s a joke, in sleep mode, you can send a long string (Length 80 ormore), that string can made module wake up, and you will receive “OK WAKE” stringfrom UART. Note: That wake up string is better not include any AT commands.7.2 Long press system KEY 1000 ms.After wake up module, you can send and receive AT commands.How to let module into sleep mode?1.Send “AT SLEEP” string through UART, if all is okay, module will return
HM Bluetooth module datasheet“OK SLEEP” string and into sleep mode.2.Execute “AT PWRM1” command, Module will auto into sleep mode whenpower on or disconnect from remote device.System advert packetIn iOS system you can’t get model MAC address directly. So we put MAC addressinformation into advert packet.You can use CBAdvertisementDataManufactureDataKey property to get it, MACaddress information string format like follow:Total length is 8 Bytes, First of two bytes is identify string, it always is 0x48 and0x4D, the rest 6 bytes is MAC address stringFor example: 0x48, 0x4D, 0xB4, 0x99, 0x4C, 0xXX, 0xXX, 0xXX0x48 and 0x4D is “HM” string.0xB4: 0x99: 0x4C: 0xXX: 0xXX: 0xXX is BLE MAC Address.System KEY function (PIO0)Press if Low 1000ms:7.3.1 If Module is in sleep modeModule will wake up immediately, if AT NOTI value is “1”, module will send“OK WAKE” string through UART.7.3.2 If Module has already connected to remote deviceModule will disconnect from remote device.
HM Bluetooth module datasheet7.3.3 If Module is standby modeModule will reset to default configuration. Then restart.System LED function (PIO1)In sleep mode, LED has turned off.If AT PIO10 is setupUnconnected status: Output High 500 ms, Low 500 msConnected status: Output HighIf AT PIO11 is setupUnconnected status: Output Low.Connected status: Output High.System work ModeA) Mode 0(Transmission mode):Before connect, you can configure module parameters with AT CommandsAfter connect, you can send and receive Bluetooth data through UART.B) Mode 1(PIO acquisition mode):Before connect, you can configure module parameters with AT CommandsAfter connect1) Send and receive Bluetooth data through UART.2) Remote device could configure module parameters with AT Commands3) Remote device could control PIO2 and PIO3 output low or high with ATCommandsHM-11 has no this function4) Remote device could get PIO4 11 input status with AT CommandsHM-11 only has PIO2 and PIO3.C) Mode 2 (Remote control mode):Before connect, you can configure module parameters with AT CommandsAfter connect:1) Send and receive Bluetooth data through UART.2) Remote device could configure module parameters with AT Commands3) Remote device could control PIO2 11 output low or high
